Smart Move: Argentines have been perfecting bus travel since the 1920s, when colectivos were among the first public buses in the world. For the 13-hour, overnight ride from Buenos Aires to Mendoza, you’ll have a fully reclining leather seat (think airline first class) and your choice of wine and meriendas—sweet and savory snacks like pastries and small sandwiches (first-class ticket, $65, plus meals; omnilineas.com).
Dine Right: Steak is to Argentina as pasta is to Italy: everywhere and always excellent. But no restaurant does it better than Cabaña Las Lilas, in downtown Buenos Aires (laslilas.com). Entire sides of beef and piles of sausages sizzle on a massive wood-fired grill in the middle of the steakhouse, and when you bite into your rib eye, you’ll actually taste grass—Argentine cows don’t do corn.
